LlFTlNG DEVICE FOR STOVES OR RANGE S SPECIFICATION forming part of Letters Patent No. 650,810, dated May 29, 1900.

Application filed January 6, 1899. Renewed November 278, 1899; Serial N0. 738 614. (N0 model.)

To all whom it may concern:

Be it known that I, SAMU L CHARLES EN- TWISILE, a citizen of the United States of America,- residing at Pittsburg, in the county of Allegheny and State of Fennsylvania, have invented certain new and useful Improvements in Lifting Devices for Stoves or Ranges, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain new and usef ul improvements in lifting devices for stoves.

My invention relates particularly to a device primarily adapted for use upon stovelegs, one object being to provide the stove-legs with means for readily raising the same on rollers, so the stove can be easily moved to any position desired, and also for lowering the same in such a position as to conceal the rollers by the stove-leg.

A further object of my invention is to provide a stove-leg with a pair of supports or guides for the lifting device, the said guides or supports being cast integral with the inner face of the leg, one above the other, and wherein the elevating parts shall be simple and not liable to get out of order. I

Briefly described, my invention consists in providing a stove-leg with a pair of guides or supports formed integral therewith on its inner face which are suitably apertured to receive the pintle-rod of the caster to allow the same to operate therethrough and also providing the inner face of the leg with a pair of outwardly-extending lugs or projections which are adapted to receive the support and form bearings for the shaft, upon which is mounted an eccentric for the elevating of the stove, and secured to the ends of the shaft the operating-lever, which is operated from-the outside of the stove-leg, and the lower end the handle of the lever rests normally upon the lower or converging end of the stove-leg when the stove is in a lowered position and rests against a portion of the stove when the stove is in an elevated position.

Other objects and advantages of the invention will hereinafter appear, and the novel combinations will be specifically defined in the claim hereunto appended.

The invention resides in the combinations and the construction, arrangement, and ad aptation of parts, all being hereinafter more fully described, and particularly pointed out in the appended claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views thereof, and in which-=- Figure 1 is a front View of the stove-leg and a portion of the base of a stove, showing the position of the operating-lever for the raising mechanism when the stove is in a lowered position. Fig. 2 is a side view thereof, showing the position of the raising mechanism in full lines when the stove is in a lowered position and the dotted lines its position when the stove is in an elevated position. Fig. 3 is a back view of a stove-leg, showing my improved raising mechanism as attached thereto. Fig. 4 is a perspective view of the operating-lever secured to the shaft carrying the eccentric. Fig. 5 is a perspective view of a stove-leg, showing my improved elevating mechanism as attached thereto and a portion of the operating-lever therefor. Fig. 6 is a perspective view of the lower bracket, which is adapted to be secured to the upper bracket cast integral with the stove-leg for supporting as well as forming a bearing for the operating-shaft. Fig. 7 is a perspective view of a modified form of bearing and supporting means formed integral with the inner face of the stove-leg for securing the operating-shaft in position.

Referring to the drawings by reference-numerals, 1 indicates a portion of the base of a stove to which a supporting-plate 2 for the stove-leg 3 is secured. This plate may be secured in any desirable manner, but as shown is apertured, as at 4, to receive the fastening means which operate therethrough and connect with the base portion of the stove. The preferred form of stove-leg is of convex shape, as shown, and the lower end thereof converged outwardly at 5.

Formed integral with the inner face of the stove-leg are a pair of guides or extensions 6 and 7, the extension 6 being of less length than the extension 7, and these extensions are apertured to allow the pintle S to operate therethrough. The pintle 8 has secured to its lower end the roller or caster 9 and has also arranged thereon between the two extensions the stop 10, which consists of a suitable strip of metal projecting outwardly on each side thereof. This stop 10 is adapted to limit the downward movement of the pintle.

Formed integral with the inner edge of the stove-leg, on each side thereof, is the bracket 11, having a semicircular groove formed on its lower face to receive the one end of the operating-shaft 12, and secured to the lower face of this bracket 11 by any suitable means is the lower bracket 13, which also hasformed therein on its upper face a semicircular groove which coincides with the groove formed on the lower face of the upper bracket. These grooved portions in the brackets form a bearing-surface for the end of the shaft.

The operating-shaft has mounted thereon the eccentric 14, which is always adapted to normally rest against the upper end of the pintle of the caster or roller. Connected to the ends of the operating-shaft 12, on each side thereof, is the lever 15. This lever is formed of a suitable metallic bar, bent in the manner shown. The lower end thereof, as at 16, rests upon the projecting end 5 of the stove-leg when in a lowered position.

In Fig. 7 I have shown a modified form of bearing for the operating-shaft 12, and it consists of a pair of lugs or projections 17, formed integral with the inner face of the stove-leg, which are bent downwardly, as shown, to receive the operating-shaft 12, which is mounted in the recess 18 and held in its position by the weight of the stove bearing against the same.

It will be observed that the operating-lever is always on the front of the stove-leg, whether in a lowered or raised position, and will overcome the inconvenience of operating the lifting device from the rear of the stoveleg, as heretofore used in devices of this kind. It will also be observed that, owing to having a pair of extensions or guides formed to allow the pintle to operate therethrough, the same will prevent the bending of the pintle when the stove is either raised or lowered. This also overcomes the defects heretofore in devices of this kind.

It is thought that the many advantages of my improved lifting device over the devices of this character heretofore in use and also its operation can be readily understood from the foregoing description, taken in connection with the accompanying drawings.

It will be observed that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a lifting device for stoves, the combination of astove-leg, a pairof extensions formed integral with the inner face of said stove-leg, one above the other,a pintlepperating through said extensions having a roller or caster secured to its lower end, an operating-shaft carrying an eccentric adapted to be brought into contact with the upper end of said pintle, means for securing the said shaft in position formed integral with the inner face of said legs, and an operating-lever connected to each end of said shaft adapted to be operated at the front of a stove-leg, substantially as shown and described.

In testimony whereof I aflix my signature in the presence of two witnesses.

S. CHARLES ENTlVISTLE.
